Thoughts about Holland Radial Baffle muzzle brakes?

[BroncoMustang]

I have heard some good things about the Holland's Radial Baffle Muzzle Brakes. I later read an interesting article on the Precision Rifle Blog entitled "Muzzle Brakes: Ability to stay on target." Other than one sort of radical design the Holland Radial Baffle Muzzle Brake appears to do the best at staying on target, which for long distance shooting, I would think is an important element to consider. The article is located at:

What experience has anyone out there had with these muzzle brakes? I would be interested to hear and learn from your experience(s).

They work good as long as you do not shoot in prone.
Any brake with openings on the bottom is horrible in prone.

The Holland brakes work extremely well and don't have any openings on the bottom. They direct the gasses rearward so they are highly efficient at recoil reduction.
I use one of Darryl's old designs called a supermagnum iirc and it is a fantastic brake. I called to get another one and he said the design was dropped because it didn't work as well as his new designs.
The old design had an expansion chamber that I liked alot but it had radial holes that kick up dirt which most don't care for. I use mine for hunting so it's never been an issue.

I have them on 2 deer rifles(7mm & 280AI). I think they are great but since the gasses go rearward be sure to have good ear protection for you and your buddies. Took a class from him, had to use one of his rentals with brake because my barrel heated up to much after 2 shots ( have since re barreled)
Shooting 10/16" steel targets from 100 to 800 yards was made even more fun being able to see bullets hit target.
